Variant Chrome — Keeping the Scroll-Deck Pill Lean as the Menu Grows

Adding the third scroll deck pushed the header's variant-toggle pill onto two lines: the label and the counter were stacking. A two-attribute fix to the inline counter span keeps everything on one horizontal line, so the chrome stays lean vertically as the menu of full-deck variants continues to grow. Small change; durable principle: the navigation surface should scale with the catalog, not the other way around.
